Figure 2. Picture of Nikon Coolpix 950 Digital Camera
Pictures were opened at 3dvista Studio by order. After
alignment and stitching process, we got panorama. Panoramic
image was converted to a video file. The file extension is mov.
It’s well-known file format for Quick Time Player. So we
managed to convert an image file to video file. It gives
opportunity to use easily because of common video file format.
End users don’t encounter any problem to play the movie file.
Table 1. Database was obtained at third block directory
3. INTEGRATION OF PANORAMIC IMAGE
To obtain video documentation, several steps were
implemented:
1. Photographs were taken so that panoramic image can
be obtained.
2. Point which photos were taken measured by handheld
GPS.
3. Digital photos were transferred to computer in order
to build panorama.
4. Point which was measured by GPS was determined at
TIS as node graphic data.
5. At the layer, Panoramic image was linked to database.
All steps were applied by order according to some detail which
emphasis at below.
3.1 Building Panoramic Image
Sultanahmet square was chosen for panoramic image. A lot of
place such as Blue Mosque, Hagia Sophia Museum and other
historical monuments were taken because of wide vision
capabilities of panorama. Therefore, opportunity was given to
show a lot of monument. To build panorama, digital camera
Nikon Coolpix 950 (Figure 2), tripod were used. Trial version
of 3dvista studio was also used as software. While photograph
point was chosen, we paid attention to catch best view best
point. So all important monument could be showed at one
image.
Taking photo is beginning from Sultanahmet Mosque. After
rotating 360 degree we reach Sultanahmet Mosque view again.
Preceding image overlapped following image at most %50.
Therefore, a cylindrical panorama was obtained. Figure 3
illustrates structure of cylindrical panorama.

3.2 Determining Coordinates with GPS
After measurement with handheld GPS, we obtained ED50
datum Cartesian coordinates. The Cartesian coordinates should
have projected to 3 degree Gauss-Kruger Cartesian coordinates.
First, ellipsoidal Cartesian coordinates were converted to
ellipsoidal geographic coordinates. Then, Gauss-Kruger
Conform Projection was calculated from ellipsoidal geographic
coordinates. Table 2 and Table 3 illustrate coordinates and
projection result for GPS measurement.

3.3 Transferring of Panorama to TIS
Coordinates which were obtained above, were pointed at video
documentation layer. Database type was the same as preceding
database. So, file path name was entered as data (Table 4.).
Figure 4 explains how to provide integration between panorama
and TIS. Perspective view of Historical peninsula is showed in
